An example apparatus includes a first detector configured to generate a first digitized stream of pulses and a second detector configured to generate a second digitized stream of pulses; a first packet decoder configured to decode a first valid over-the-air packet from the first digitized stream of pulses and generate a first time-stamped tag data packet; a second packet decoder configured to decode a second valid over-the-air packet from the second digitized stream of pulses; an arbiter configured to receive at least one of first and second time-stamped tag data packets and to select a time-stamped tag data packet from the at least one of the first and second time-stamped tag data packets; and a packet formatter to formulate a network data packet based on the selected time-stamped tag data packet.
